UV Fused Silica Substrates for UV, Laserline & Broadband Applications
UV Grade Fused Silica is synthetic amorphous silicon dioxide of extremely high purity providing maximum transmission from 195 to 2100 nm. This non-crystalline, colorless silica glass combines a very low thermal expansion coefficient with good optical qualities, and excellent transmittance in the ultraviolet region. Transmission and homogeneity exceed those of crystalline quartz without the problems of orientation and temperature instability inherent in the crystalline form. It will not fluoresce under UV light and is resistant to radiation. For high-energy applications, the extreme purity of fused silica eliminates microscopic defect sites that could lead to laser damage. For more information, refer to our optical materials Technical Note
High Quality Precision Plano-Convex Lens Surfaces
Our ultrafast plano-convex lens UV fused silica substrates are polished to tight tolerances minimizing wavefront distortion. Tight surface quality tolerances minimize scatter and unwanted diffraction effects. These lenses have a 20-10 scratch-dig surface quality, and a λ/8 surface irregularity. For more information, refer to the optical surfaces technical note.
Ultrafast Optimized Antireflection Coating
Our broadband ultrafast optimized antireflection coating is optimized specifically for 660-1380 nm ultrafast laser wavelengths to provide low GVD performance. Typical transmission performance of the AR.UF coating is shown compared to an uncoated lens and our standard AR.16 and AR.18 coatings covering similar wavelengths.
Standardized Plano-Convex Focal Lengths
Standard effective focal lengths across a variety of newport lens sizes, materials and shapes provide a systematic approach allowing for lenses of different sizes to be interchanged without requiring other changes to your optical system. Collimating a point light source coming from the planar surface or focusing a collimated light source which is incident on the curved surface will help to minimize the spherical aberration.
Plano-Convex Lens Shape for Focusing Light
Plano-Convex lenses are the best choice for focusing parallel rays of light to a single point. They can be used to focus, collect and collimate light. The asymmetry of this lens shape minimizes spherical aberration in situations where the object and image are located at unequal distance from the lens. The optimum case is where the object is placed at infinity with parallel rays entering lens and the final image is a focused point.
Focusing a Collimated Laser Beam
For an application example, let’s look at the case of the output from a Newport R-31005 HeNe laser focused to a spot using a KPX043 Plano-Convex Lens. This Hene laser has a beam diameter of 0.63 mm and a divergence of 1.3 mrad. Note that these are beam diameter and full divergence, so in the notation of our figure, y1 = 0.315 mm and θ1 = 0.65 mrad. The KPX043 lens has a focal length of 25.4 mm. Thus, at the focused spot, we have a radius θ1f = 16.5 µm. So, the diameter of the spot will be 33 µm.
Collimating Light from a Point Source
Since a common application is the collimation of the output from an Optical Fiber, let’s use that for our numerical example. The Newport F-MBB fiber has a core diameter of 200 µm and a numerical aperture (NA) of 0.37. The radius y1 of our source is then 100 µm. NA is defined in terms of the half-angle accepted by the fiber, so θ1 = 0.37. If we again use the KPX043 , 25.4 mm focal length lens to collimate the output, we will have a beam with a radius of 9.4 mm and a half-angle divergence of 4 mrad.
Low Group Velocity Dispersion Performance
Mounted Version - with Lens Tubes
The lenses can be mounted in LT series lens tube for constructing a complex optical system or quickly connecting to other threaded lens mounts: A-Line™ series fixed lens mount, or adjustable lens positioner (with thread adapter). Use LT-WR series spanner wrench for easy lens installation.
